A Search for Deuterium Recombination Line Emission from Orion A(10),
Abstract
Line emission from DCN was recently detected in the direction of the Orion Nebula. If DCN and HCN are formed and destroyed at the same rate, the D to H ratio is 0.006. This ratio should result in a detectable recombination line of deuterium. The author searched unsuccessfully for the D92alpha line and placed a limit (D)/(H) > 0.0016. The present results suggest that HCN and its isotope have different rates of formation and destruction. (Author)
